Specification of Letters Patent.

Patented Oct. 14, 1913.

Application filed November 25, 1512. Serial No. 733,255.

To all whom it may concern Be it known that I, Jenn B. YOUNG, a subject of the Kingdom of Great Britain, residing at North Crystal Lake, in the county of McHenr and State of Illinois, have invented new and useful Improvements in Vacuum-Cleaners, of which the following is a specification.

This invention relates to vacuum cleaners, and more particularly to that class of vacuum cleaners which are portable and hand operated.

T re main objects of this invention are, first, to provide a portable, hand-operated vacuum cleaner, in which the vacuum apparatus and nozzle may be operated with one hand; second, to provide a vacuum cleaner in which the pump handle or lever is utilized in moving the nozzle across the surface from which the dust and other light particles are to be moved, and, third, to provide a vacuum cleaner of which the nozzle may be operated by the pump lever or may be handled independently thereof.

To such ends this invention consists in the several novel features hereinafter fully set forth and particularly defined in the claims.

The invention is clearly illustrated in the drawing furnished herewith, in which- Figure 1 is a perspective view of a complete vacuum cleaner, embodying one form of the present invention; Fig. 2 is a view of a fragment of the pump lever and connection between the same and nozzle, and showing a simple form of joint between the lever and the connection, and Fig. 3 is a detail cross-section through the nozzle, showing its connection with a flexible tube.

Referring to said drawing, which shows one embodiment of the present invention, 10 designates the base, preferably comprising two longitudinal members, 11, and cross pieces 12, 13, secured to and connecting said longitudinal members. To the under side of the members, 11, is secured a pair of rollers, 11 to facilitate movement along the surface to be cleaned. Said base supports a hand-operated vacuum mechanism of any well-known form, of which 1 1 designates the vacuum pump cylinder; 15, the piston rod, and 16, the pump lever which is fulcrumed upon an arm, 17, secured to the base. The upper end of said pump lever is provided with a handle, 18, which may be grasped by the hand in oscillating the pump lever to produce a partial vacuum in the cylinder 14. The nozzle, 19, is located at a short distance beyond the front end of the base, and is connected with the pump cylinder by a flexible connection, 20, preferably in the form of an ordinary rubber tube, one end of which is secured upon a nipple, 21, that projects up from the nozzle, 19, and the other end of said tube is secured to a nipple, 22, of an inlet cap, 23, which is removably secured to a neck, 25, of the cylinder, 14, at its intake end. In accordance with the usual practice, a dust bag, 2st, is provided at this point and its upper end is secured between the neck, 25, and cap,

A bypass, 26, projects up from the cylinder, 14, and may be employed. as a handle for carrying the cleaner about.

The nozzle, 19, is provided on its under side with a dust inlet slot, 19, and in the form shown in the drawing, said nozzle eX- tends transversely of the base; the nozzle and the pump lever are connected together by a connecting device, 27, which, as shown, comprises two bars or rods, 27", one secured to each end of the nozzle and projecting upward and backward toward the pump lever, 16, the upper ends of said bars or rods, 27, converge toward each other, and are secured together as by bolts and nuts, 28. The function of the bars or rods, 27 is to couple the pump lever with the nozzle in such manner that the one moves with the other, and the upper end of said connecting device may be detachably secured to the lever, as, for instance, by means of a hook, 29, upon its upper end, which hooks over the pin, 30, held by a U-shaped clip, 31, which is se cured to the pump lever, 16. The connecting device, 27, is held between the two sides of the clip when hooked upon the pin, 30.

In operation, the pump lever, 16, is swung back and forth to produce the necessary vacuum in the pump cylinder, the flexible connection, 20, and the nozzle, 19, for remov ing dust from the surface over which the nozzle is passed. By reason of the operative connection between the pump lever and nozzle, the latter is moved back and forth across the surface upon which it rests, whenever the pump lever is operated, and by moving the entire structure occasionally to bring the reciprocations of the nozzle over other parts of the surface to be cleaned, the latter may be readily gone over quickly and thoroughly and the dust and dirt removed there from.

If desired, the connecting device, 27, may be detached from the pump lever and the nozzle may be moved about independently of the ren'iainder of the cleaner. It is also evident that the flexible connection, 20, and its nozzle may be detached from the cylinder, and a different form of nozzle attached thereto.

From the above, it is obvious that the operator may use either one or both hands in moving the pump lever, and that no further effort is required in directing the nozzle over the surface to be cleaned. This is a decided advantage because the nozzle is automatically takencare of and its dust slot constantly maintained in proper position to the surface over which the nozzle is being moved.

I realize that various alterations and modifications of this device are possible without departing from the spirit of my invention, and I. do not therefore desire to limit myself to the exact form of construction shown and described.

I claim as new and desire to secure by Letters Patent:

1. In a portable, hand-operated vacuum cleaner, a vacuum pump, a pump lever therefor, a nozzle connected to said pump by a flexible tube, and a rigid nozzle guiding de vice connecting said nozzle with said pump lever.

Copies of this patent may be 2,. In a portable, hand-operated vacuum cleaner, a vacuum pump, a pump lever therefor, a nozzle connected to said pump by a flexible tube, and a rigid nozzle guiding device rigidly secured to said nozzle and detachably secured to said pump lever.

3. In a portable, hand0perated vacuum cleaner, a vacuum pump and its pump lever, a nozzle connected to said pump by a flexible tube, and a rigid nozzle guiding device rigidly secured to said nozzle and pivotally secured upon said pump lever.

4. A portable, hand-operated vacuum cleaner comprising a vacuum pump having a pump lever, a nozzle connected to said pump by a flexible tube, a pair of bars, each secured at one end to said nozzle, and extending upward and backward alongside of the pump, said bars converging toward each other at their upper ends, and thereat detachably secured to said pump lever.

In a portable vacuum cleaner, a vacuum pump, an upright pump lever for operating said pump, a nozzle connected to said pump by a flexible tube, a pair of bars, having one end secured to said nozzle and the other end provided with a hook capable of being hooked upon said pump lever.
